Catalog codes and physical fit

The Group Code is R322 and the Product Group is 4095 — these are Siemens internal classification fields, not buyer-facing specs, but they confirm the part sits in the RFID/identification category. Packaging dimensions are 78.2 x 124.2 x 29.2 mm; the reader body itself is 90 x 62 x 25 mm (LxWxH) per the description. The integrated antenna is inside the housing, so no external antenna cable or tuning is needed.

Frequently asked questions

What are the key frequency and protocol capabilities?

LF at 125 kHz supports HITAG 1/2/S and EM41xx transponders. HF supports ISO 14443 A/B and ISO 15693. Both bands are handled by the integrated antenna in a single reader.

How is the reader powered and connected?

Primary power and data are over a single RJ45 connection using Power over Ethernet (PoE). A 24 V DC supply is also supported as an alternative.
